Trader consensus on Polymarket reflects tight uncertainty for Guangzhou's highest temperature at Baiyun International Airport on April 17, with implied probabilities clustered around 26–29°C driven by the latest China Meteorological Administration short-range forecasts projecting a maximum near 26°C under persistent cloudy conditions. Recent observations show April 16 highs reaching 29°C amid overcast skies, but model ensembles anticipate moderated diurnal heating from high humidity (around 80–85%), light southerly winds, and scattered showers limiting solar insolation. Differentiating factors include potential afternoon cloud breaks boosting 28–29°C outcomes versus prolonged cover favoring 26°C or below; historical mid-April averages of 26–27°C align with this range. Evening updates from CMA and localized urban heat island effects at the airport could refine trader positioning before resolution.
